STEM-WINDING WATCH.

SPECIFICATION forming part of Letters Patent No. 353,687, dated December'7, 1886.

Application filed January 9, 1886. y Serial No. 188,080. (No model.)

To all whom it may concern:

Beit known that I, ABRAHAM L. KELLER, a citizen of the United States,residing at El gin, in the county of Kane and State of Illinois, haveinvented a new and useful Improvement in Stem- Winding and Hand-SettingMechanism for Vatehes, of which the following is a specification.

My invention relates to improvements in stem-winding and hand-settingmechanism in which the works of the watch can be shifted and changed foreither aright or left hand person. In other words, when the watch isheld in either right or left hand that the dial will be in an uprightposition.

My improvements further relate to the arrangement and constructions ofthe gear meehanism, that by pulling the knob or crown button near thependant ring the mechanism changes from the winding to the hand-settinggear, and a push on the crown-button causesk the mechanism again toresume its normal position with the winding-gear.

[It further consists in a gear-ring having an internally-toothed ratchetandmounted loosely in a pendant swinging yoke which operates in conjunction with the endwise-moving crown stein.

The object of my improvements are, first, to enable any watchdealer orjeweler to change the mechanism to suit for either'a right or lefthanded person by simply reversing the winding and setting gears andmoving the Works around one-quarter turn in the watchcase; second, insimplifying the mechanism and having an easy-moving action; third, byhaving a positive yand reliable action, not likely to get out of order.I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure l is a full top view of the gear side of awatch with my mechanism in its normal place. Fig. 2 is also a full topView of the gear side of a watch with my mechanism in gear with thegear-wheel on the hand-arbor. Fig. 3 is a top plan of my geararrangement with the top plate removed. Fig. 4 is also a top plan of mygear mechanism partially in section taken on the line Y Y of Fig. 5, and5o Fig. 5 is a transverse section taken. on the line X X of Fig. 3.Figs. 6, 7, and 8 are detail views of my mechanism.

Similar letters of reference refer to similar parts throughout theseveral views.

In the drawings, 7c is a knob or crown-but ton next to the pendant ring,but is independent of it, and movable with a rotatory motion,

as well as an endwise motion, on the axis or crown-stem Z of thiscrown'knob. There is a bevel-pinion,r, having a square hole to receivethe stem, which stem has a corresponding square formed on its end toreceive said pinion. rThe said pinion acts by means of an intermediatepinion, f, having both bevel and' spur cogs, and this acts on agear-ring, d,

ratchet-wheelA g act with a corresponding ratchet h, loosely mounted ona square stud, 0, that is rigidly secured t0 the top plate, b, (SeeFigs. 5 and 8,) and a spring, F, holding said ratchet in gear with theratchet g, thereby preventing the unwinding of the mainspring as thewinding has been completed. This completes the winding-up part of thewatch. That for setting the hands consists of a pinion, e, attached tothe arbor of the minutehand. This pinion, it must be observed, is freeof the gear-ring d, or, in technical language, not in gear with it, butit can be put so by simply pulling the crown-knob k on the end of thependant until it stops moving out. This causes the bifurcated lever s,by means of the collar m, to act on the stud e, that is rigidly sefcured on the arbor 'v of the pendant swinging yoke z. 'This action onthe stud z will cause the geared ring d to move from its normal po`sition and fall into action with the pinion e, as shown in Figs. 2 and4.. The click t, by means of the pin a on the bfureated lever near itspivot, holds said wheels in gear until the adjustment of the hands iscompleted. In the IOO meantime the winding-ratchet g has been disengagedfrom the action of the gear-ring (Z, as shown in Fig. 4. Vhen thesetting of the hands has been completed,a push on the crownstem willrelieve the bifurcated lever s from the stud e', and the springe willcarry the gearring d to its normal position and hold it in action withthe winding-ratchet g.

The object of making theteeth of the ratchet g on the hooked plan is forthe purpose to prevent slipping in winding up the watch,and therebypermit the use of a light spring for holding winding-gear in action, andalso to prevent injury to the watch should the Winder turn thecrown-stem in the wrong direction.

A sleeve, n, its loosely over the collar m on the crown-stem Z, and ison one side slotted to admit of the bifurcated lever s to engage thecollar on said crown-stem. This sleeve serves to hold the bevel-pinion rto its place when the crown-stem is moved endwise, and also permits oftaking the works of the watch out of its case without removing thecrown-stem from the pendant by simply removing the plates a and a.

vThe plates a and a are so constructed that the pinions o' and f, thependant swinging yoke Z, the bifurcated lever s, its click t, and thesleeve n can readily be changed to either side of the windingdrnm g,(see Figs. 8 and 4, j and y,) and thereby make it either a right or lefthanded watch, at the option of the dealer or jeweler. W'hen this changeis made from right to left hand, the works are moved in the caseonequarter of a turn, as indicated in the dotted lines w, Fig. 2. Thiswill then change the position of the dial in relation to the pendant ofthe watch and present the dial in an upright position when held by thependant in the left hand by the'wearer.

The intermediate pinion,f, is placed in the seat formed in the top ofthe plate a', and resting on the boss raised around the hole in saidseat. The upper side of this pinion has a true counterbore to tit theboss b of pendantyoke z'. (See Fig. 6.) The ends of the arbor o arepivoted in the top and bottom plates respectively. The pinion ftherefore forms its axis on the boss b of pendant-yoke Z, and therebyallows of a large hole in said pinion, to permit of the arbor c on theswinging yoke with its stud z to be readily removed. By thisconstruction the entire winding and setting mechanism can readily betaken apart by simply removing the top plate, a, and the mechanismadjusted from right to left han-d, or vice Versa.

Having thus fully described my invention, what I therefore desire tosecure by Letters Patent is 1. The combination, with the end wisemovingstem Z, having its end formed in a square to receive the pinion o'thereon, of the intermediate pinion, f, provided with both bevel andspur cogs, as shown, and operating in conjunction with the gear-ringfZ,and pend ant swinging yoke/,constructcd, arranged,and operatingsubstantially as and for the purpose set forth.

2. The combination, with the endwise-mov- 7o ing stem Z and bevel-piniono', of the double intermediate pinion, j", internally and externallygeared ring (Z, externally and crown ratched Wheel g, stationarycrown-ratchet li, spring P, stationary square stud o, and pendantswinging yoke t', these members being combined for' operationsubstantially in the manner and for the purpose set forth.

3. The combinatiomwiththependantswinging yoke t, having arbor c, andforming the axis of the intermediate pinion, f, of the stud z, placed onthe arbor c, below the said pinion, and operating in conjunction withthe bifurcated lever 8 or its equivalent, and the endwise-movingcrown-stem Z, combined and arranged for operation substantially as andfor the purpose set forth.

4. The externally and internally geared ring eZ, mounted in thependantswinging yoke t', and operating in combination with the endwise androtatory moving crown-stem, for the purpose set forth.

5. The externally and crown faced ratchet wheel g, rigidly fixed to thestem of the winding-drum q, and operatingin conjunction with acrown-faced ratchet, h, movably fixed on a stationary square stud, o, orits equivalent, a spring, P, for holding said ratchet in gear, for t-hepurpose described, combined with the externally and internally gearedring (Z, mounted in a swinging yoke, for alternately engaging anddisengaging with the ratchet g by the crown-stem, for the purpose setforth.

6. lThe combination, substantially as hereinbefore set forth, of theendwise and rotatory. moving crown-stem Z, bifurcated lever s, click t,pendant swinging yoke i, sleeve n., bevelpinion r,intern1ediate pinion,f, externally and internally geared ring cZ, gear-wheel e, spring c,externally and crown faced ratchet g, crownratcheth, spring P, andwinding-drum stem, combined and arranged for operation as shown, for thepurpose specified.
